Optical parametric oscillator pumped at ~one µm with intracavity mid-IR variance-frequency technology in OPGaAs
A person observes a extraordinary boost in technology of the 2nd harmonic together with the demodulation signals as opposed to the pump wave amplitude. A transparent correlation exists among these nonlinear signatures and the level of damages. Preliminary determinations of the coefficient of quadratic nonlinearity have already been obtained. The final results from the configuration of parametric emitting antenna are considered for being the quite 1st on cracked materials.
This technique will allow the operation of commonly tunable optical parametric oscillators2 (OPO) and subsequent distinction frequency generators3 producing tunable pulses of large peak power. The higher Electrical power in the pump pulse trains has sure benefits with the Procedure of the synchronously pumped OPO, e.g., peaceful stability demands, as well as probable to operate with big cavity losses (e.g. metallic mirrors) making it possible for significant tuning ranges with just one set of mirrors and high output-coupling things for pulse shortening.
The significant conversion performance and big selection of radiation wavelength tuning permits to assume this material may well compete with AgGaS2, AgGaSe2, ZnGeP2 and GaSe crystals Despite the appreciable problem of huge dimension crystals progress procedure.
On this get the job done, we existing exactly what is, to our expertise, the very first measurements of the quantum period diffusion sound of the cw OPO. Read a lot more
We report the implementation of a KTP optical parametric oscillator pumped by a pulsed Ti:sapphire laser. Which includes sign and idler, it could be constantly tuned from 1.261 by way of two.532 μm by different the pump wavelength. Two major enhancements have been reached, including the connection of your sign and idler tuning ranges as well as the superior output pulse Vitality in the signal and idler tuning ... [Display complete abstract] ranges. The initial improvement was achieved by identifying two specific sets of period-matching angles. The second enhancement was understood through the use of five sets of resonator mirrors for oscillating both sign or idler.
Though working with an institutional account for this Web-site we don’t track any personal, overall performance, practical or 1st or third party related information and facts.
We existing a numerical research for the design of productive MgO:PPLN primarily based pulsed nanosecond optical parametric oscillator (OPO), with enter pump pulses of major-hat transverse intensity profile, and also a double-pass pump cavity configuration. Particularly, we examine the effect of area shape on the conversion efficiency. We deemed two types of domain structures: "perfect vertical-wall" and "wedge-formed" domains and our numerical success exhibit that at bigger pump pulse energies, the conversion effectiveness saturates, along with the saturated performance is nearly unbiased from the area designs.
The particular warmth and thermal conductivity of HgGa2S4 are calculated. It can be concluded the blended Houses of HgGa2S4 crystals can offer for them a number one place One of the components used in nonlinear-optical products for mid-IR-frequency conversion.

Basic strategy for reducing the depolarization loss ensuing from thermally induced birefringence in stable-state lasers
twelve μm and explain all frequency conversion techniques understood thus far with them along with long term probable applications. Keyword phrases: Ternary and quaternary semiconductors, defect chalcopyrites, solid remedies, nonlinear optical crystals, mid-infrared
A pulsed TEA CO2 laser was used to investigate the effect of pump radiation parameters (mode structure, wavelength, and pulse period), concentrating disorders, absorption coefficient, and temperature over the performance of conversion into the second click here harmonic and on angular dependences of phase matching in ZnGeP2 crystals. Superior agreement betweeen experimental and theoretical results is observed. Browse extra
3% rms more than twelve h in very good beam good quality. The in close proximity to-IR signal pulses within the OPO Possess a Gaussian pulse duration of �?19 ps , calculated at 1284 nm. We now have investigated the temperature tuning features on the OPO and as opposed the data With all the theoretical calculations using The newest Sellmeier equations and thermo-optic coefficients with the crystal. To the very best of our expertise, Here is the first picosecond OPO dependant on CSP operating at MHz repetition rates.
